title	Harnessing Design Space: A Similarity-Based Exploration Method for Generative Design
source	International Journal of Architectural Computing vol. 13 - no. 2, 217-236
summary	Working with multiple alternatives is a central activity in design; therefore, we expect computational systems to support such work. There is a need to find out the tool features supporting this central activity so that we can build new systems. To explore such features, we propose a method that aims to enable interaction with a large number of design alternatives by similaritybased exploration. Using existing data analysis and visualization techniques adopting similarity-based search, we formalized the method and its elements by focusing on systematic filtering, clustering, and choosing alternatives. We present a scenario on developing conceptual designs for a residential apartment to illustrate how the method can be applied, as well as to reveal the limitation of current tools and the potential interactive clustering and filtering features for the new systems coupled with parametric design.

title	Architecture, Design and Information Visualization (Data): different phases of data between the perception and clarification
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 451-458.
summary	The article develops a reflection on the different stages of information (data) in the relations of mediation between ‘individual interpreter’ and ‘information systems’, and the agency of the processes of perception, interpretation and clarification. The goal was to identify, understand and describe how ‘information systems’ enact the different stages of articulation of ‘information’, from “propensity” to ‘concatenation’, and from ‘critical’ to the ‘action’. Tests and analysis of the effects of ‘information systems’ were observed in ‘narrative accounts’ of ‘individual interpreter’. However, the conclusion is that the social conformation of ‘strategies for obtaining information’ prevails on the properties of ‘information system’.

title	Augmented Reality in the Viewing of Architectural Design Solutions
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 192-196.
summary	Architecture is an area of study in which design solution visualization is essential. It is during the design phase that the projective doubts are clarified. Augmented Reality (AR) enables the visualization of virtual elements in the real environment. In this paper, visualization strategies will be presented in Augmented Reality for the discussion of alternatives design solution in architecture. These strategies are presented in an experiment in which perceptions of users are observed through a workshop. We compare two display strategies (AR mobile x AR projected) in four types of representation. As a contribution, we present a critical analysis of the benefits and limitations of the strategies used.

title	Empirical Evaluation of Three Wind Analysis Tools for Concept Design of an Urban Wind Shelter
doi	https://doi.org/10.52842/conf.caadria.2015.313
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 313-322
summary	The aim of this investigation was to evaluate the performance of three wind analysis programs used in the early design stage (EDS) of a passive windbreak shelter concept for an urban context. This study compared the different workflows of these programs and the respective visualized results, identifying the differences and limitations of these tools, for design exploration. The programs tested were Autodesk Vasari, ODS-Studio, and ANSYS CFX. The results of this investigation indicate that basic computational fluid dynamics (CFD) programs such as Vasari was found to be more suitable for the observation of large-scale wind phenomena through the whole area of the shelter. Moreover, intermediate CFD tools (functions, usability) such as ODS-Studio can be used more efficiently in detailed visualization of wind interacting with design features. Finally, a more sophisticated CFD program like ANSYS CFX can be incorporated in the early design stage workflow for final verification of results.

title	An Integrated Performance Analysis Platform for Sustainable Architecture and Urban Infrastructure Systems
doi	https://doi.org/10.52842/conf.ecaade.2015.1.315
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 315-324
summary	This applied research brings together the performance analysis of a building's micro-scale and urban-infrastructure's macro-scale. A New York City lot, is serving as the background of experimentation with parametric design, performance simulation, data analysis and visualization. The paper describes the process of integrating design intentions, location parameters, climate data, material properties, and space quality and sustainability metrics into one platform. Although in-depth domain knowledge is irreplaceable, the paper argues that the exploration into contemporary, easily accessible and algorithmic simulation software, provides a unique educational opportunity for architects and students to integrate performance driven design in their every-day practice, and become aware of the consequences of their design on urban infrastructure systems. This allows them to reduce the time frame between design iterations and performance evaluation for the benefit of better informed decisions.

title	Virtual Sketching: Instructional Low Resolution Virtual Reality Simulations
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 506-513.
summary	This research paper describes the implementation of virtual reality immersive simulation studios in academia, facilitated by the use of the “Virtual Sketching Method” (VSM). The VSM allows the basic expression of architectural forms and the perceptual experience of interior and exterior spaces. It fosters simulations based on render-less (low resolution) visualization in contrast to other simulation workflows based on render-more (high resolution) visualization techniques. It bridges between different types of media and supports iterative cycles of formulation, prototyping, and assessment. The paper reports on students’ learning outcomes and their qualitative correlation with the VSM usability and effectiveness in design learning.

title	Data-Insight-Driven Project Delivery: Approach to Accelerated Project Delivery Using Data Analytics, Data Mining and Data Visualization
doi	https://doi.org/10.52842/conf.acadia.2017.102
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 102-109
summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

title	Heuristic Optimization in Design
doi	https://doi.org/10.52842/conf.acadia.2015.357
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 357-369
summary	This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title	Decorative Robotic Plastering - A Case Study of Real-Time Human Machine-Collaboration in High-Skill Domains
doi	https://doi.org/10.52842/conf.ecaade.2015.2.383
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 383-388
summary	This paper explores hybrid digital / physical workflows in the building trades, a high-skill domain where human dexterity and craft can be augmented by the precision and repeatability of digital design and fabrication tools. In particular the paper highlights a project where historic techniques of decorative plastering are extended through live motion capture of a drawing implement, information rich visualization projected in the space of fabrication, and custom robotic tooling to generate free-form running moulds. This workflow allows designers and craftspeople to quickly explore patterns through free-hand sketch, test ideas with shaded previews, and seamlessly produce physical parts using robotic collaborators.

title	Hybrid Sentient Canopy: An implementation and visualization of proprioreceptive curiosity-based machine learning
doi	https://doi.org/10.52842/conf.acadia.2016.362
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 362-371
summary	This paper describes the development of a sentient canopy that interacts with human visitors by using its own internal motivation. Modular curiosity-based machine learning behaviour is supported by a highly distributed system of microprocessor hardware integrated within interlinked cellular arrays of sound, light, kinetic actuators and proprioreceptive sensors in a resilient physical scaffolding system. The curiosity-based system involves exploration by employing an expert system composed of archives of information from preceding behaviours, calculating potential behaviours together with locations and applications, executing behaviour and comparing result to prediction. Prototype architectural structures entitled Sentient Canopy and Sentient Chamber developed during 2015 and 2016 were developed to support this interactive behaviour, integrating new communications protocols and firmware, and a hybrid proprioreceptive system that configured new electronics with sound, light, and motion sensing capable of internal machine sensing and externally- oriented sensing for human interaction. Proprioreception was implemented by producing custom electronics serving photoresistors, pitch-sensing microphones, and accelerometers for motion and position, coupled to sound, light and motion-based actuators and additional infrared sensors designed for sensing of human gestures. This configuration provided the machine system with the ability to calculate and detect real-time behaviour and to compare this to models of behaviour predicted within scripted routines. Testbeds located at the Living Architecture Systems Group/Philip Beesley Architect Inc. (LASG/PBAI, Waterloo/Toronto), Centre for Information Technology (CITA, Copenhagen) National Academy of Sciences (NAS) in Washington DC are illustrated.

summary	The complexity of today´s architecture solutions brings the need to integrate, in the design process, digital tools for creation, visualization, representation and evaluation of design solutions. This paper proposes the adoption of a new Virtual Reality (VR) tool, referred to as VIARmodes, to support the architectural design process with an improved communication across different specialities, towards the facilitation of the project decision process. This tool allows a complete visualization of the design, specifically useful during the detailed design phase, including the architecture design and of other engineering specialities, progressively and interactively adapting the project visualization to the information needed for each discipline. With a set of 3 different visualization modes simulated in real scale within a Virtual Environment (VE), and adopting natural human-computer interaction by using speech, the system allows a team of architect and engineers, to visualize and interact with the proposed design during a collaborative design brief. We carried a usability evaluation study with 12 architects. The study showed that the tool was perceived to be effective and its use efficient during the design process, especially during the detailed design phase.

summary	The problem at hand is to ensure that the perception by means of Augmented Reality (AR) is hence reliable and opinions resulting from a Participatory Design (PD) mediated by this technology could be incorporated into the design solution. This paper presents the evaluation of multiple 3D models recognition in AR, with or without an auxiliary projection. Leisure area designs involve urban equipment of various dimensions that are visualized simultaneously. Therefore, it was necessary to verify if the participants were capable of recognizing them and which would be the best way to visualize: exclusively with the iPad screen or with the iPad associated with an external projection – to verify whether the visualization using an external projection would amplify the visualization area. The results obtained in the evaluation were used to improve the AR application and also, to develop guidelines for the AR use in a PD.

title	Accuracy and Ambiguity: Geometric reconstruction of a seventh century stone temple in Hanchey, Cambodia
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 190-202.
summary	Modeling the fragmented and heavily eroded remains of early temple architecture poses several challenges in accurate reconstruction of shape and form from digitally acquired datasets. This paper describes a collection of stepwise ad-hoc modeling methods that can re-assemble ambiguous and fragmentary evidence to provide a robust and empirical platform for the reconstruction of ruined temples. The paper presents the results of the method and the degree of accuracy and ambiguity in the acquisition, processing and reconstruction phases. A key aspect of the method is the maintenance of multiple “ground truths” from plural sources of partial evidence. Key findings of the paper demonstrate early results from the manipulation of geometric modeling primitives based on point collections, an advance in extending the classical tools of architectural analysis and comparison. The problem of accuracy and ambiguity in these methods and their algorithmic implementation is the subject of further investigation.

summary	This paper presents an Augmented Reality application intended to establish a link to site history, approaching cultural heritage issues simulating the metaphor of time tunnel. It presents an initiative to bring technology to the end user, in order to rescue the past through AR of a plaza with cultural importance that suffered intervention with time. The work was developed as an exercise of a Virtual Reality class in a Graduate Program. The class exercise involved understanding uses of AR, development of AR applications and user perception of the built environment through the augmented lenses provided by AR applications. The method proposed for the exercise was the field study developed in seven steps: AR scope definition, preliminary exploration, AR application formulation, data collection and user perception evaluation. Four AR applications were developed and evaluated: 360 panorama and an overlap image, 3D object, and video with historic information. On site, users demonstrated surprise with the experiment and no difficulty of use, however transposition to the significant record of a past time varied with AR application and simplification of implementation.

title	Augmented Reality Design Decision Support Engine for the Early Building Design Stage
doi	https://doi.org/10.52842/conf.caadria.2015.231
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 231-240
summary	Augmented reality has come a long way and experienced a paradigm shift in 1999 when the ARToolKit was released as open source. The nature of interaction between the physical world and the virtual-world has changed forever. Fortunately for the AECO industry, the transition from traditional Computer Aided Design to virtual building design phrased as Building Information Modeling has created a tremendous potential to adopt Augmented Reality. The presented research is situated in the early design stage of project inception and focuses on supporting informed collective decision-making, characterized by a dynamic back and forth analytical process generating large amounts of data. Facilitation aspects, such as data-collection, storage and access to enable comparability and evaluation are crucial for collective decision-making. The current research has addressed these aspects by means of data accessibility, visualization and presentation. At the core of the project is a custom developed Augmented Reality framework that enables data interaction within the design model. In order to serve as a collaborative decision support engine, the framework also allows multiple models and their datasets to be displayed and exercised simultaneously. The paper demonstrates in the case study the successful application of the AR tool during collaborative design decision meetings.

title	A Computational Design Framework Supporting Human Interaction with Environmentally-Responsive Building Envelopes
source	International Journal of Architectural Computing vol. 13 - no. 1, 1–24
summary	Emerging materials present opportunities to fundamentally shift current expectations of dynamic building envelope functionality towards systems that can respond to occupant needs while meeting the energy demands of buildings. In order to assess the environmental, social, and architectural opportunities that are increasing with responsive building envelopes, new tools are needed to simulate their multi-performance capabilities. This paper describes a computational design framework to support human interaction with environmentally-responsive electroactive dynamic daylighting systems. The objective is to develop algorithms for variable solar control and visible transmittance that simultaneously address occupant preferences for visual effects and interaction. Results demonstrate that energy performance and user satisfaction are not mutually exclusive and can be co-optimized. The effectiveness and limitations of the computational framework in assessing strategies to balance environmental performance and human interaction are discussed. Conclusions present areas of ongoing work that integrate multi-user interactions and immersive visualization techniques with multiscalar energy modeling tools.

title	Pattern, cognition and spatial information processing: Representations of the spatial layout of architectural design with spatial-semantic analytics
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 484.
summary	In this paper, we review and extend the idea of Alexander’s “pattern language”, especially from the viewpoints of complexity theories, information systems, and human-computer interaction, to explore spatial cognition-based design representations for “intelligent and adaptive/interactive environment” in architecture and urban planning. We propose a theoretic framework of design patterns “with spatial information processing”, and attempt to incorporate state-of-the-art computational methods of information visualization/visual analytics into the conventional CAAD approaches. Focused on the spatial-semantic analytics, together with abstract syntactic pattern representation, by using “spatial-semantic aware” graph grammar formalization, i.e., Spatial Graph Grammars (SGG), the relevant models, algorithms and tool are proposed. We testify our theoretic framework and computational tool VEGGIE (a Visual Environment of Graph Grammar Induction Engineering) by using actual architectural design works (spatial layout exemplars of a small office building and the three house projects by Frank Lloyd Wright) as study cases, so as to demonstrate our proposed approach for practical applications. The results are discussed and further research is suggested.
